Crispy baked flounder is the perfect weeknight meal! Serve it with a fresh salad and your favorite sides for a simple, well-balanced dinner. It’s a delicious way to change up your dinner routine, and it’s packed with heart-healthy fats.

How to make walnut & pistachio crusted flounder

Here’s what you’ll need for this simple recipe:

• flounder fillets- this recipe would also be delicious with sole, or even salmon!
• seasoned breadcrumbs
• walnuts & pistachios- I like to crush them in a bag using the bottom of a jar, but you can lightly pulse them in a food processor to chop them up
• dijon mustard
• honey- I love using a spicy honey for an extra kick

The fish comes out crisp and flakey, and is a delicious way to eat more seafood during the week. I can’t wait for you guys to try it- I know you’re going to love it!
